Space Invaders sets off an arcade boom beginning in Japan
Taito released Tomohiro Nishikado's game of descending aliens, which sped up as the player cleared it and kept a record of high scores. It filled Japanese arcades, spawned dedicated venues, and later transformed Atari's console.

What happened
Nishikado designed the game and much of its hardware himself, importing a microprocessor because nothing available in-house could move that many objects. The aliens accelerated as their ranks thinned, not by intention but because the processor had less to draw and simply ran faster. He judged the effect an improvement and kept it. A four-note bass figure repeated underneath, speeding up with them, which is among the earliest uses of continuous music to apply pressure rather than to decorate.
Japan responded on a scale nobody had planned for. Cafés converted tables into cabinets, venues opened stocked with nothing but this one machine, and the game was blamed for keeping teenagers out of school. A story about demand causing a national shortage of hundred-yen coins circulates constantly and is now generally treated as exaggeration, though the underlying phenomenon worried parents and newspapers plainly enough. Escalating difficulty and a score table gave players reason to return, which is what operators actually cared about.
In the United States the game arrived through Midway and did well, but its larger effect came in 1980, when Atari licensed it as a cartridge. That was the first arcade hit brought home under license, families bought the console specifically to play it, and the industry learned that a conversion could sell hardware. Console makers afterward chased arcade licenses relentlessly, a strategy that shaped home gaming until arcades themselves declined.
The world at the time
Japanese arcades before 1978 leaned on electro-mechanical games and imported American designs, with video cabinets a modest part of the business. Domestic manufacturers had the electronics expertise to build their own once processors made it practical. In the United States arcade earnings were healthy, but the floor was still dominated by driving games, ball-and-paddle variants and pinball.
Historical significance
Two industries were remade. In Japan the game established the arcade as mass entertainment and pushed Taito's competitors toward screen-based cabinets rather than mechanical ones. In the United States it turned a struggling console into a mass-market product. The high-score table also invented public competition on a machine, ancestor of every leaderboard since.
What it changed
Cabinets stayed profitable for years and the game was ported to essentially every platform over the following four decades. Its silhouette became the medium's visual shorthand, printed on clothing and used on museum posters. The boom also drew Japanese electronics firms into games seriously, and within two years one of them released the maze chase that widened the audience further.
